In case folks are still moving over, reminder I'm over there too, still doing all the electronics, embedded, rust, and protocol stuff I've always been doing :)

The first episode of the "Self-Directed Research Podcast" with me and @fasterthanlime is now up! The podcast is a weekly deep dive, and this first episode is Amos exploring what they got right, and what they got wrong, when it comes to Rust build...

Hey, just a rememinder: I'm pretty active over on the other site, and as of today, you no longer need an invite to sign up!

It would be cool to see more Rust and Embedded folks over there.

Cohost and Bluesky are my favs right now, and Matrix is always a good choice.

If you find anywhere that has a bunch of embedded and/or rust folks there, lemme know :D

Update, added bluesky to my list of websites. Find me there if you'd like. (I don't have invites)

Still most active on Cohost and Matrix. Full list of places to find me in the linked tweet.

Extremely avionics brain What if I started using a part numbering scheme for all the silly things I make, so that I can track them using tags and stuff. A company I worked for used the scheme: xxx-yyyyy-zz Where xxx was the "kind" of thing, e.g. an assembly, or a certain kind of document, or a full product; yyyyy is the "project id"; and zz is a major revision/iteration document id of that thing. Overengineering? Probably, you really only need this if you have/want/are required to maintain a document control system. But maybe I do?

okay but what if I set up a doc control system for my insane personal projects

For no reason at all, if you haven't heard of "Chesterton's Fence" before, this might be an interesting, topical read.

In particular, it's important to understand systems (and how and why they came to be, for better or worse), before changing them.

A simpler way to calculate Euclidean Rhythms Euclidean Rhythms [https://dbkaplun.github.io/euclidean-rhythm/] are a cool way to generate beat patterns, originally shown to me by @jjbbllkk. There's a paper (pdf) [http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf] that describes a way to calculate it, by shuffling the beats and rests to make sure they are well spaced. There IS a rust crate that does this, but it follows the paper's methods fairly directly, which requires a bunch of SmallVecs, and I don't love it: https://github.com/padenot/euclidian-rythms/blob/3c72f37ff8a6c1b7897fdc783e52fabe8eb45dc8/src/lib.rs#L5-L72 [https://github.com/padenot/euclidian-rythms/blob/3c72f37ff8a6c1b7897fdc783e52fabe8eb45dc8/src/lib.rs#L5-L72] Instead, I have hit the problem with loops and bit math, which allows me to handle the problem much more comfortably on embedded systems: pub struct Euc32 { interval: u32, data: u32, } impl Euc32 { pub fn new(hits: u32, interval: u32) -> Option<Euc32> { if hits == 0 { return Some(Euc32 { interval, data: 0 }); } if (hits > 32) || (interval > 32) || (hits > interval) { return None; } let mut ctr = 0u32; // TODO: There's probaby a *math* way to do this without // a loop, but whatever while ctr < interval { ctr += hits; } let mut data = 0; for i in 0..interval { if ctr >= interval { data |= 1 << i; ctr -= interval; } ctr += hits; } Some(Euc32 { interval, data }) } } This gives me the results I expect: test euc::test::sevens ... 0: [.......] 1: [x......] 2: [x..x...] 3: [x.x.x..] 4: [x.x.xx.] 5: [xx.xxx.] 6: [xxxxxx.] 7: [xxxxxxx] ok test euc::test::thirteens ... 00: [.............] 01: [x............] 02: [x.....x......] 03: [x...x...x....] 04: [x..x..x..x...] 05: [x..x.x..x.x..] 06: [x.x.x.x.x.x..] 07: [x.x.x.x.x.xx.] 08: [x.xx.x.xx.xx.] 09: [xx.xx.xx.xxx.] 10: [xxx.xxx.xxxx.] 11: [xxxxx.xxxxxx.] 12: [xxxxxxxxxxxx.] 13: [xxxxxxxxxxxxx] ok

Continuing my sleep deprived audio hacking, figuring out how to calculate Euclidean Rhythms, but very efficiently:

Been hacking on some stuff for my generative synth, primarily how to build/store musical notes.

I also wired it up so it can:

A: generate midi of the stored contents
B: you can use a tool (MuseScore) to dump the midi to music notation

This is mary had a little lamb

wait why are the bluechecks actually blue and not white now?

it's still the same for both paid and "classic" verified accounts.

(this is rhetorical, I know none of it actually makes sense)

GitHub - cyrozap/rv51: A RISC-V emulator for the 8051 (MCS-51) microcontroller. A RISC-V emulator for the 8051 (MCS-51) microcontroller. - cyrozap/rv51

Someone made an RV32I VM for the 8051, which means you can write Rust binaries that target RV32I, and run them on an 8051.

That's just, whew. Is it a good idea? I have no idea! Is it badass? Yes, very much so.

alt text (I guess I do have to explain it): someone has used a fourier series of rotating divs to simulate the HTML marquee element. In practice, this causes an eggbug to scroll from right to left (a little twitchy/bouncy), then the series swings it down and back right to reset)

* Their current profile contents
* Their twitter accountID?

I have my export, but that ONLY has accountIDs, and no way to map that to account/names

Just came up with an awesome URL pun name, and while the domain is available, it's 325 EUR.

It's a funny joke, I just don't know if it's a 325 EUR funny joke.

I take a weird pleasure in writing things like “y’all’s” in semi-formal communication.

In context: “regarding y’all’s project,”
